Abstract
Using strong cation exchange simulated moving bed (SMB) chromatography, a nitrogen-phosphate-potassium (NPK) fertilizer is produced in a cost-effective manner. The SMB process operated in a non-traditional way is divided into production and regeneration sections for exclusion of undesirable ions, and composed of six zones including two wash-water zones. This paper addresses modeling and simulation studies on the ion-exchange SMB process, comparing simulation results with experimental data obtained both from a pilot plant and an industrial plant. The simulation results show a good agreement with in situ experimental data obtained in the two plants. The model equation validated by the experiments will be applicable for optimization problems to obtain optimum operating conditions of the process.
